Clarify which you mean:
| Game | Platform | TCG Relevance |
|---|---|---|
| Pokémon Scarlet / Violet | Switch | In-game TCG minigame (not full TCG); trade/battle via internet |
| Pokémon Legends: Arceus | Switch | No TCG |
| Pokémon TCG: Card Dex (app) | iOS/Android | Collection scanner/manager; not playable |
Bottom line: If you want the **official, playable, current Pokémon TCG video game in the US** → **Download Pokémon TCG Live (PTCGL) for free.** It's actively supported, cross-platform, and the only way to play the real TCG digitally.
